Findings on Endoscopic Retrograde Cholangiopancreatography and Pancreatic Function Test in Suspected Chronic Pancreatitis and Negative Cross-Sectional Imaging

ePFT is a sensitive test for the diagnosis of patients with suspicion of CP and negative or inconclusive cross-sectional imaging. ERCP has modest sensitivity and high specificity for this purpose. A normal ePFT rules out CP with a high degree of certainty. An abnormal test result requires follow-up evaluation and diagnostic confirmation.
